YORK, n. Y., AssIeNoR ToumrEn SHOE MACHINERY To all whom it may concern.

Be it known that I, GEonoE ,F. lVoLEE, a citizen'of the United statesi fesiding at New York, in the county of NewYork and State of New York, have invented certain new and useful Improvements in Edge Gages for Stock-Fitting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in" the art to which it appertains to make and use the same.

The present invention is an-impro'vemen't in stock fitting machines and more particularly in edge gages for use on machinesof this type. v p

lVith the edge gages in general use, it is diflicult to feed the sole as the work engaging surface of the gage has to be small enough to enter the smallest radius in the periphery of any sole to be operated upon. With such a small work engaging surface a soft sole is indented by. the gage and this causes the correct position of the Sole to be lost. This objection to the gages now in use is principally noticeable when operating upon insoles which are often of soft material, but it is also found in some outsoles, particularly cacks which are irregular in outline and in which the curves are sharp. If the bearing surface of the gage is made with a large radius to prevent indenting the sole, it will not enter the sharp curve at the shank and relation of the tool to the solI edge is lost.

It is the object of this inventionLto remedy these difiieulties. In accordance with this object a feature of the invention oomprises the provision of an edge gage having a plurality of ad ustable sole engaging points with means for relatively adjusting these points to conform to the sharpest curve at the shank in the particular stylegof sole being operated upon. In the best form of the invention known to the inventor, the gage bar is provided with three sole engaging rolls and means for adpisting the two outside rolls with respect to the central roll so that the line of contact of these rolls with the sole may be made to conform to the shank curve of the smallest radius.

The invention will best be understood from the following description and accompanying drawings and will be particularly pointed out in the appended claims.

Specification of Letters Patent. Patented Jun 25, 1912, Application filed February 15, 1911. Serial No. 608,811. g i

The preferred embodiment of the invention 1s lllustrated 1n drawings, 1n whichthe accompanying Figure 1 is a plan view of the improved edge gage 1n operative relation to a sole; lug. 2 1s a side elevation, on an enlarged stock fitting operations. carriesa. freelv rotatahle roll 2 mounted in a support 3. Two 1 similar rolls 4 and 5 are mounted in the forked ends of a block (3 which adapted to slide upon a tongue 7 on the bar l. The

- slot 8 formed in the block (1 by the roll carrylng forks receives the roll support a so that the rolls 4- and 5 are at each side of the roll 2. A shoulder screw 9. threaded into the bar 1, engages a slot in the block (3 and assists in guiding the block in its in and out movements.

' The means for adjusting the rolls l, and .7 may consist of a screw 10 ha ring a knurled thumb nut 11 and a stemll rotatahlv tixed in the bar I by means of a groove in the stem and a pin 13. The screw 10 engages a tapped hole 14in the block (.1.

In the use of this edge gage the operator "will turn the thumb nut ll until the rolls J: and 5 touch the sole when the roll 2 is at the will be possible to ha to the three roll nearly in a straight line. On soles hating sharp ronravities in their peripherr. which are the most dillit-ult to feed. the three l'()ll. will be so adjusted that the curvature of their longitudinal contact surface will he su stantially parallel to the sharpest cont-mitt of the sole edge, thereby giring the greatest freedom of novenwnt to the sole. When a change is made in the style of sole being up erated upon, the gage is again adjusted so that the same conditions prevail. In each instance the gage presents a large bearing surface to the sole edge but in turning the le lhoh--harp curve are easil negotiated and the proper working position of the sole l. maintained.
